摘　　要：目的：测定切除卵巢大鼠后肢骨不同部位骨量丢失的情况。方法：应用双能Ｘ线吸收法动态观察切除卵巢大鼠及对照组大鼠后肢骨不同部位骨密度。结果：实验组术后４周即可在股骨远端检测到明显的骨量丢失，与对照组比较差异显著。Objective:To measure the bone loss in tibia and different regions of femur in ovariectomized (OVX) rats. Methods: The BMD in tibia and different regions of femur of OVX rats and controls with DEXA were observed dynamically. Results: Significantly bone loss in distal femur was detected at 4 weeks in OVX rats. Conclusion: Bone loss in distal femur is most obviously seen.
